Calculate the heat loss of the area to be heated. It is recommended that one of the following methods be used: ASHRAE Guide and Data Book (The American Society of Heating, Refrigeration & Air Conditioning Engineers); The NEMA Handbook (The National Electrical Manufacturer's Association); or the ACCA Manual J (The Air Conditioning Contractors of America). The layout of the space to be heated must be taken into consideration to determine the selection of the best size heater and air displacement. Most applications benefit from a combination of vertically and horizontally discharged air delivery. In buildings with large doors that are frequently opened, use a high velocity heater with horizontal air flow across the opening, or use an infrared heater. In smaller areas where comfort is a prime consideration, more heaters of smaller capacity are recommended. Smaller KW heaters are also recommended for low mounting heights to avoid discomfort and increased noise levels. Additionally, there is better air distribution by using a greater number of lower KW heaters.

Horizontal Air Flow – Position heaters to allow the air flow to "wipe" the exposed walls without blowing directly against the wall. Spacing between the heaters should be approximately 1.5 times the "air throw" of the heaters (approx. air throw is 12').

Vertical Air Flow – When vertical discharging heaters are used exclusively, the air streams must overlap to blanket outside walls and provide good heat distribution. Vertical air flow is best used for areas with high ceilings or bays. Vertical discharging units are to be mounted high above machinery, assembly lines, etc. Vertical discharging units are best used when the perimeter heat loss is adequately controlled.

Ordering Information:Model CEH005-P, (1 Phase) is designed to use a C600M, C600S or a CEKTB2 thermostat. If you add the jumpers, as shown on the heater wiring diagram (supplied with instructions and in wiring compartment) you can use a Single Pole 22 amp wall stat or a CEKTB1 thermostat. USE ONLY C600M, C600S, OR A CEKTB2 FOR 3 PHASE hookup on this model.

Approximate air throw is 12'. The CEH is recommended for elevations under 7500 feet
